You can just wrap the rope twice in the krab to choke it single line, rather than having to tie anything, the prussic can come in very handy though.

Only hit 29c here again, due to hit 39 again on thursday still no rain more bush fires breaking out.

Just curious mate, i ask alot of questions, plus before i buy something i tend to research as much as i can about it so i can really make up my mind, also i find it helps me pick out the right choice for the right job, knowing your rope types and constructions can come in handy when making homemade stuff.

Had a skylotec then got a treemotion theres a reason everyone uses it and it does last if treated well. The skylotec is comfortable but is large and i found it cumbersome good for hanging in but not the best for pruning. The treemotion is a nice middle ground enough support and padding to hang in for a decent time but not restrict you enough when you are moving around a dense canopy.

Tachyon is a trade name for the construction of the rope which has a braided cover a braided core and then a third braided core in order to keep it round, Teuflberger bought out NEropes so they are the same company, however the teachyons are all different, the Teuflberger version is pretty static and very hard in the hand where the NE version is soft in the hand but bouncy as hell, think it might have something to do with the Ne version getting made in the US and the teuflberger version getting made in Europe.

Its called a Slaice its not spliced its a dyneema loop inserted in to the rope which is then tucked into the cover and stitched, Kermantle ropes have their strength in the core, and the outer sheath is to protect it, thats why kernamntle lines are recommended with ascenders. I tried the fly its nice in the hand and stays very round due to its construction but its seriously bouncy. Its been around for a while(2001) and is considered by some a very outdated rope. Also platinum is a double braid with the cover woven through the core at certain increments to stop the rope milking etc so its considered unsplicable and im not sure if they would bother slaicing it as its not a climbing line.

NOOO the wrench should never ever be used to engage the hitch, the hitch should be short enough and the thether long enough that when you stop the hitch grabs at the same time the wrench engages if its jerky its your hitch that needs sorting. In this video kevin describes what the wrench shouldnt do, [ame=http://www.youtube.com/watch?v=NFUXXHNzMJ0]SINGING TREE ROPE WRENCH - Safety Concepts - YouTube[/ame] This shows how the system should engage [ame=http://www.youtube.com/watch?v=nhQTBe2OPvQ]Zk-2 rope wrench w stiff tether - YouTube[/ame]

Simon you don't ever want to use the wrench to engage the hitch you need a shorter hitch cord tied so it grabs every time, that thether needs to be longer, you can just use a small bit of elastic with a micro biner to tend the wrench it's small simple and tucks under your t shirt when not in use. Tommy, you can splice this tethers up using hollow braid pretty easily, just getting the lengths of the legs right is the tricky part. Sent from my GT-I9300T using Tapatalk 2

WHat John means is once you have cut it into a 3m lenght you will have 2m thats pretty useless, wrap with electrical tape cut with sharp scissors or knife then seal the end with superglue or melt with a lighter.

You might have to clip a micro karabiner in the middle hole to stop the legs bending. Looks good though mate chuck leccy tape over it then it will cover all the whipping up.

Apparantly he wasnt getting paid for the Oprah interview.

Hit 40c again here today currently half 8 in the evening and is still 30c and is going to stay that way untill tomorrow morning then its going to hit 35c yay HOT!

It was 29 today and it's 39 tomorrow we have had 0.2mm of rain so far this year, it's seriously hot here. Sent from my GT-I9300T using Tapatalk 2

You are getting mixed up with Dynamic and static forces, In double rope you are hanging in the sytem with x1 at the anchor point you have mechanical advantage so your only pulling half your weight up with still only x1 at the anchor point, ignore double rope for now and rigging, if your on a base anchor its your weight either side to hold you up resulting in x2 at the anchor point if you have wraps around a capstan and are holding a it as the rope exits it will be easier to hold but that doesnt mean the force isnt there, imagine grabbing the single line going into the capstan from above its still going to be the same weight, the friction doesnt negate the force at the anchor point or the opposing leg. If you base anchored climbed up and went through 5 re directs they would be sharing the load but it would still be double and the load on the anchored side of the line would still be the same as the force you have applied to the line.

The rope doesnt run in the system if you wrapped it around one branch 10 times you still going to have the same force applied to that point, if it was spread over 10 different branches the force would be dissipated over those anchor points, Adding wraps in a rigging situation doesnt change the weight of the limb it makes it easier for you to handle, In order to stop the limb from dropping you need to hold the line statically, yes the friction helps you but it doesnt change the weight of the limb if the line was no longer held static no matter what the wraps the limb will drop. The force will stay the same regardless of how many times you wrap it around the limb, all it changes is how easy it is to be held at the base of the tree the overall force at the top will still be double that of the climbers weight.

Imagine if you hung on one side of the rope weighing 100kg, what would take to stop you falling to the ground? another 100kg, so when its over the limb in base anchor set up in order to hold you 100 kg up the same force has to be exerted on the other side, resulting in doubling the force on you anchor point. If you choked your line e.g. running bowline that is only 1x your force as its is a straight pull down on the rope no other opposing force is required in order to keep you in place, the same princible is applied to Ddrt but the main difference is that the load is shared between two legs of line resulting in the load being split at your splice and friction cord. In reference to your comment about friction in terms of lowering you are reffering to dynamic forces which will increase in some rigging situations i dont believe its a fair comparison compared to anchoring an srt system as that is static, but regardless, By adding wraps you are not changing the force applied to the limb the force is always there all you are doing is decelerating the limb as it falls the limb still weighs the same and is still applying the same force to the limb. Imagine if you were being lowered out on a belayable system, when lowering you down your weight its going to stay the same all that will change depending on the size of the limb is the friction required to slow you down.

In DDrt you are your suspended over a limb so you have a hundred percent of your weight on that limb then the load is shared between your spliced eye and friction cord etc, the friction at your anchor point wouldnt change the force exerted on said point just allows you to hold your weight as the branch takes some friction, Imagine how much friction it would take in order to hold 100 kg with the other end not attached, i think the friction on the branch would make an almost negligible amount of difference, the most important thing in SRT or SRWP is understanding the forces behind what you are doing and knowing your tree species. When anchoring over more than one branch its important to remeber that you could be pulling the stems together or exerting force over the weaker axis of the tree so just be smart and climb safe!

Well the rope is static so i dont think it would make a difference.

Haha good point mate

Yeah i was looking for a good diagram, on the web but couldnt find one.

Ddrt only puts your weight on the anchor point, where as a base anchored Srt system will exert 2x the force on the anchor point thats why its encouraged not to isolate your line, i wouldnt say you could exert the same force Ddrt on your anchor point as you could with a base anchored srt system.

The clip has been designed so it doesn't clip a second bight of rope into it either locking your rope off or the rope falling out of the clip, those sailing shackles don't last long I found the small ring used for realising the clip breaks easily. Sent from my GT-I9300T using Tapatalk 2
